Submitting QSOs From a Logging Application

All of the applications listed below can export a file that can be digitally signed by TQSL.  Some of these applications can directly upload your QSOs to LotW, and update logged QSOs to reflect their acceptance and confirmation by LoTW. The ARRL does not recommend one application over another. You should review the features of each each application to decide which one best suits your operating style.

If you need help with one of these applications, please contact the developer or support organization.  The ARRL's LoTW Help Desk does not support logging applications or any other third party software.
